Definitions

  • the present invention relates to a leader to be attached to the leading end of a film for leading the film, methods for attaching the leader to a film and for detaching it therefrom, and a developing apparatus with automatic attachment and detachment of the leader.
  • the aforementioned conventional developing apparatus involves a problem that time and labor are needed for attaching the leader to the film and the splicing tape must he exfoliated after completion of the film processsing.
  • the apparatus presents another problem that time and labor must he taken for setting the leader attached to the film on the apparatus.
  • an object of the present invention to overcome the foregoing problems and to provide a leader capable of heing attached to and detached from a film without using a splicing tape, methods for attaching the leader to and detaching it from the film, and a developing apparatus with automatic attachment and detachment of the leader which realizes development of the film by merely setting a cartridge accommodating therein a roll of the film photographed on the apparatus at a predetermined position.
  • a leader to be attached at one end portion thereof to a film having an engagement perforation in a leading end portion thereof, comprising:
  • a method for attaching the aforesaid leader to the film comprising the steps of:
  • an apparatus for automatically attaching the leader to the film comprising:
  • an apparatus for automatically detaching the leader from the film comprising:
  • a film having an engagement perforation at its one end portion can be easily set on the leader by merely inserting the film into an elongated opening of the leader.
  • the leader is held as curved, and the film is drawn out of a cartridge and inserted into the elongated opening of the leader, whereby the leader is attached to the film.
  • the leader is detached from the leader by drawing the film while collapsingly pressing the pawl of the leader.
  • a leader 1 comprises a thin plate having a flexibility and is adapted to he attached at its one end portion to a film 2 for leading the film 2 to go round in a development processing part of a developing apparatus.
  • the leader 1 includes a pawl 3 in the end portion to which the film 2 is to he attached, an elongated opening 4 formed nearer the end of the leader than the pawl 3, and a pressing plate 5 mounted on the leader body to cover the elongated opening 4 and pawl 3.
  • the film 2 is rolled and supported within a cartridge 6, and the tongue portion of the film 2 is cut off in advance.
  • An elliptic engagement perforation 7 is punched at an approximate central of the end portion of the film 2 on the side where the tongue portion is cut off in advance.
  • the engagement perforation 7 is adapted to engage the pawl 3. Note that the engagement perforation 7 might be reinforced by bonding a tape to the portion to be punched of the film 2 and then punching that portion.
  • the pawl 3 of the leader 1 is positioned at a location allowing engagement of the pawl 3 with the engagement perforation 7 of the film 2 which is inserted through the elongated opening 4.
  • the pawl 3 is projected upwardly with its tip 3a oriented in a direction in which the leader 1 is to be fed.
  • the pawl 3 is formed by cutting a semi-ring-shaped hole and then upwardly bending the semi-circular portion resulting from the cutting at its root portion 3b.
  • the leader 1 is made of any material having a flexibility and exhibiting a characteristic such that a portion once plastic-deformed by bending maintains resilence to some extent.
  • the pawl can he collapsingly pressed and, upon released from the pressing force, can restore its bent condition. Such behavior is needed to detach the film 2 from the leader 1, and the detachment of the film from the pawl 3 can be easily achieved by drawing the film 2 with the pawl 3 kept collapsingly pressed.
  • the leader 1 is not made of such material, the pawl 3 might he formed in a separate member of the aforementioned properties by bending a tip of the member and bonded to the leader at its root portion. Since the tip 3a is oriented in the leader feed direction, the film 2 will not be disengaged from the pawl 3 even if the film 2 is drawn in the leader feed direction (indicated by arrow A).
  • the elongated opening 4 is formed nearer the end of the leader 1 than the pawl 3 in such a manner that a longitudinal axis thereof extends parallel to the end edge 1a of the leader 1.
  • the length of the elongated opening 4 is slightly larger than the width of the film 2. As shown in Fig. 1, the film 2 is inserted from below the leader 1 through the elongated opening 4, so that the engagement perforation 7 of the film engages the pawl 3.
  • the pressing plate 5 is provided to cover the pawl 3 and the elongated opening 4, presses the film 2 inserted through the elongated opening 4 to allow it to slide on the surface of the leader 1, guides the film 2 so that the engagement perforation 7 thereof will engage the pawl 3, and prevents the film 2 from coming off. For this reason, a hole 8 for exposing the pawl 3 is formed in the pressing plate 5 so as to prevent the pressing plate 5 from pressing the pawl 3 down and the film 2 from coming off.
  • the pressing plate 5 is bonded to a leader surface 1b lying on the side opposite to the side where the elongated opening is formed with the pawl 3 intervening between these sides.
  • the leader 1 has in its central portion a series of rectangular holes 1c equidistantly spaced from each other. These rectangular holes 1c are adapted to engage a sprocket provided within the development processing part of the developing apparatus. Hence, when the sprocket rotates, the leader 1 is fed.
  • Fig. 2 To be described with reference to Fig. 2 is a method for attaching the aforementioned leader 1 to the film.
  • the leader 1 In Fig. 2, the leader 1 is in its turned-over condition where the pressing plate 5 lies on the lower side and the elongated opening 4 on the upper side.
  • the end portion of the leader 1 to which the film 2 is to be attached is made to curve so that the pressing plate 5 lies inside the curve and that a transverse axis of the elongated opening 4 extends in the circumferential direction of the curve.
  • the leading end of the film 2 is then inserted into the elongated opening from the outside of the substantially circular arc thus formed at an appropriate angle with respect to the transverse axis of the elongated opening 4. In this way, the insertion of the leading end of the film 2 into the elongated opening is facilitated. Further, the leading end of the film 2 heing inserted is brought into contact with the pressing plate 5, then directed toward the leader surface, and made to slide on the leader surface, so that the engagement perforation 7 of the film 2 engages the pawl 3 without fail.
  • the automatic leader attacher apparatus 9 includes a leader set cover 20; leader feed means A having a spring 21, a leader feed roller 22a and a leader feed motor 22; leader backing means B having a leader guide 23 defining an arcuate path, a drive roller 24 and a solenoid-type presser 25; film feed means C having a leader controlling part 26, a solenoid-type film presser 27, a drive motor 28 and a film feed roller 29; and film cut means having a cutter 31 and a cutting solenoid 32.
  • leader set cover 20 Within the leader set cover 20 are held a plurality of leaders same as the leader 1 shown in Fig. 1, each of which is positioned with its end portion to be attached to the film 2 being located above and with its face having the pressing plate being oriented downward.
  • Each leader 1 is biased against the leader feed roller 22a by the spring 21.
  • the leader feed motor 22 When the leader feed motor 22 is actuated to rotate the leader feed roller 22a in the direction indicated by arrow, the uppermost leader 1 advances in the direction indicated by arrow a along the leader guide 23.
  • the solenoid-type presser 25 is turned on to rotate the drive roller 24 forwardly.
  • a film inlet cover 33 is opened and the cartridge 6 is set on a support 34.
  • a bracket 36 pivots about a shaft 35, so that the film feed roller 29 is lowered.
  • the leading end of the film 2 is then placed on the film feed roller 29 thus lowered.
  • the solenoid-type film presser 27 is turned on, the film feed roller 29 rises so as to he pressed against the film 2, and then the drive motor 28 is actuated to rotate the film feed roller 29 so as to feed the film 2 by a predetermined distance.
  • the leading end of the film 2 is fed toward the elongated opening 4 of the leader 1 held as curved by the leader guide 23 at an appropriate angle, so that the film 2 is assuredly inserted into the elongated opening 4 and attached to the leader 1.
  • the leader 1 thus attached to the film 2 is fed in the direction indicated by arrow c by means of the drive roller 24 and film feed roller 29 to go round in processing tanks 37.
  • a limit switch 38 detects the rotation of the cartridge 6, whereupon the cutter 31 is caused to cut off the rear end of the film 2. Then the cartridge 6 falls into a receiver 40 and held therewithin.

  • the pawl pressing roller 45 might he in the form of a ball rotatably supported, or might be a member having a merely cylindrical or spherical surface made from a slippery material.
  • the leader 1 fed in the direction indicated by arrow d via the processing tanks and a drying chamber and attached to the film 2 passes through the guide 48 and is then held by the leader guide 41.
  • the drive motor 43 stops operating and the leader 1 is fixedly held by the leader feed roller 42.
  • only the film feed roller 46 is made to slightly rotate to cause only the film 2 to advance a little so that the center of the engagement perforation 7 of the film 2 will he aligned on the center axis of the pawl 3 so as to prevent a portion of the film 2 around the engagement perforation 7 from heing pinched by the pawl 3.
  • the solenoid-type pawl presser 44 when the solenoid-type pawl presser 44 is turned on, the pawl pressing roller 45 pivots about a shaft 49 to press the pawl 3 collapsingly. With the pawl being kept collapsingly pressed, reverse rotation of the film feed roller 46 by a predetermined distance allows the film 2 to slide on the pawl 3 and to be detached from the leader 1. Thereafter, when the leader feed roller 42 and film feed roller 46 are made to rotate, the leader 1 and the film 2 are ejected into a leader stocker 51 and a film stocker 52, respectively, and are held therein.
  • Fig. 5 is a perspective view showing the principal portion of the automatic leader detaching apparatus 10 shown in Fig. 4.
  • the leader 1 is guided to the leader guide 41 by the guide 48 and temporarily held fixedly by heing pressed against the leader feed roller 42.
